Andreas,
You are mentioning that you have no special hardware or proprietary
software. Are you sure? Recently I investigated several ways to
communicate with the PLC. I even met with Siemens sales reps.

As far as I know write access requires 
1/ Modbus card 
2/ and/or Proprietary libraries/interface software

Could you describe in more details you setup?

Thanks,
